Another in-joke of John Glen's can be found in Octopussy, his second as Bond director. Prior to working as editor and director on Bond movies, Glen had actually acted as a second unit director on some notable films, including The Italian Job and Richard Donner's Superman, the latter of which he chooses to pay tribute to in Octopussy, via a short musical cue. In the film, there's a scene in which Bond softens a window's metal bars with acid, then proceeds to bend the bars by hand. Briefly, John Williams's Superman theme can be heard as an accompaniment for Roger Moore's mighty feat of strength.
